106 Claims.

This invention relates to machines for pressing soles upon shoe bottoms and is adapted for operations such as sole laying and cement sole attaching.

Objects of the invention are to provide a machine which, while sacrificing none of the advantages provided by the machine of my prior Letters Patent of the United States No. 2,301,205, granted November 10, 1942, will be more effective and convenient in operation.

Further objects of the invention are to provide shoe and sole-locating mechanisms whereby a sole, irrespectively of size or style, may be located in predetermined relation to a sole-pressing pad, and a shoe may be definitely located with respect to the sole.

The illustrated machine comprises a solepressing pad provided with adjustments whereby its surface may be made to correspond to the longitudinal curvature of the shoe bottom and ball line gages connected together for equal and opposite movement, said gages being arranged to engage a sole of any size substantially at the ball line and to locate said sole centrally of the pad on which the sole is located. Adjacent to and above the sole gages are shoe gages which also are arranged for equal and opposite movement and are operated to locate a shoe with respect to the sole held by the sole gages. Preferably a yielding device is provided in the mechanism for operating the shoe gages to permit slight separation of the gages when positioning a shoe between them if they are too close together for that particular shoe. A V-gage for the toe end of the shoe is arranged to be moved toward the sole held by the ball gages and is arranged for lateral floating movement whereby it is able to find the toe end of the sole, means being provided to lock the sole gage in that position. Adjustably carried by the sole-toe gage is a shoe gage, the shoe gage being adapted properly to locate a shoe with respect to the sole which is in contact with the sole gage.

The illustrated machine is provided with sole gages which engage the sole in the vicinity of the ends of the breast line, preferably somewhat forwardly thereof, that is, at points where the width of the average sole is approximately one-half as wide as at the ball line, The breast line gage at the outer end of the breast line is so connected with the ball line sole gages that the breast line gage will be moved about half the distance which the corresponding ball line gage moves, provision being made for adjusting this ratio to adapt the mechanism for various styles of soles.

The breast-line gage for the opposite or inner end of the breast line is connected with the gage at the outer end of the breast line for equal and opposite movement, provision being made for yielding of that gage should it contact too soon at the inner side of the sole.

A V-sha'ped gage for the rear end of the shoe, which is arranged for movement toward and from the shoe in the direction of the longitudinal median line of the rear part of the shoe, is provided with means for locking it in engagement with the shoe, this gage being also arranged for circular adjustment about a center substantially at the intersection of the logitudinal median line of the rear part with the longitudinal median line of the forepart. g

After the shoe and sole are located with respect to each other, the shoeis'pressed upon the pad. For this purpose the illustrated machine comprises novel hydraulic mechanism for applying pressure directly to the shoeto force it against the pad and means, herein illustrated as a wedge, for locking the shoe under pressure.

Still further to insure uniform sole-attaching pressure between the shoe and sole, an inflatable bag is provided beneath the pad in which a, fluid, such as water, is forced to cause uniform pressure to be applied to the entire shoe bottom. In the illustrated machine a single operating treadle is provided the first depression of which causes the gages to be moved to operative position and the second depression of which causes the gages to be released, a valve mechanism set to apply pressure to the shoe, the locking wedge operated to maintain such pressure, the pad beneath the shoe inflated, and, after a predetermined time, the valve mechanism operated to cause deflation of the bag, release of pressure on the shoe and withdrawal of the wedge.

As illustrated, pressure is applied to the shoe by toe and heel abutments which are arranged to swing into and out of position over the shoe. To prevent accidental operation of these abutments when they are not in position over the shoe, means is provided to prevent operation of the abutments by fluid pressure unless they are in position over the shoe and to prevent full operation thereof even if they are positioned over the pad with no shoe between them and the pad.

These and other features of the invention will appear more fully from the following description In the drawings,

The illustrated machine is organized to be operated by hydraulic pressure, that is, by oil pressure, and, aside from the handling of the sole and shoe, movement of the pressure-applying abutments over the shoe and the manipulation of a single treadle, is automatic. The first depression of the treadle causes the shoe and sole gages to be operated to bring them into contact with a sole placed on the pad and to locate the sole centrally re tively to the pad, the shoe gages then being in osition properly to locate a shoe which is placed on the sole. Upon the second depression of the treadle, pressure is applied to force the shoe down against the pad and the gages are released. Next, a lower pressure is employed to operate a wedge to maintain the pressure applied to the shoe, to force water into the inflatable pad under the shoe, to lock the pressure-controlling valve mechanism in opera-' tive position and to set in operation a timing mechanism whereby,after a predetermined time, the lock is released, permitting the parts to be restored to initial positions. As indicated in Fig. 1, the machine is preferably duplex, the righthand side of the machine being arranged for operation on a right shoe and the left-hand side for operation on a left shoe. Since, however, the two sides of the machine are substantially identical except that some of the parts on one side of the machine are like mirror images of corresponding parts on the other side of the machine, the description will be confined to the right-hand side, it being understood that the other side is similar and similarly operated. The pad and the shoe and sole-locating mechanism will now be described.

Referring to Figs. 2 and 5, the machine comprises a frame or casing'4ll openat the top. Over the opening is a cover plate 42 arranged at about thirty degrees inclination to the horizontal. The pad box comprises a forepart portion 44, a shank portion 46 and a heel portion 48, the forepart portion 44 being pivoted at 50 to the shank portion 48 and the shank portion :being pivoted at 52 t0 the heel portion 48. The heel portion 48 is connected by links 54 to upstanding struts 56 at the end next to the shank portion 46 and near its opposite end is supported on a five-sided cam member 58 mounted eccentrically on a shaft 60 suported on struts 62. The shaft can be turned by a hand wheel 64 to vary the inclination of the rear part 48 with respect to the shank part 46. To vary the angular relation between the forepart 44 and the shank part 46 to adapt the longitudinal contour of the boxto accommodate the bottom of shoes which are to have heels of difi'erent heights, a wedge 66 (Fig. 5) is provided which has threaded engagement with a rod 68 carrying a hand wheel Ill by the turning of which the wedge 56 may be moved longitudinally of the pad. The movement of the wedge 66 toward the toe end of the pad box will raise the pivot 50 relatively to the pivot 52 and flatten the contour of the pad box. To permit this, the forepart 44 of the pad box is pivoted on struts 14 for tipping movemen by pins 16 shown in dotted lines in Fig. 7. The lower edge of the wedge 66, as shown in Fig. 3, is .T-shaped and arranged to slide in guides 18 and at its upper edge is slotted lengthwise at v to receive a lug 82 formed on the forepart portion 44 and provided with a pin 84 which rests on the top of the wedge.- Gibs 88 are attached to the wedge at opposite sides thereof and have portions which overhang the pin to prevent upward movement thereof. The shank portion 46, as shown in Fig. 5, has a curved surface 90 arranged to engage a complemental surface on the u r face of the lug 82 to afford additional support for the shank po'rtion independently of the pivot 50 from which as a center the curved surfaces are formed. By the described arrangement, adjustment of the wedge will positively move the pivot 50 up and down. To indicate the adjustment of the wedge, that is, the heightwise position of the pivot 50, the pivot is pointed and a fixed graduated scale 9| (Fig. 2) is arranged to cooperate therewith.

In the pad box are arranged the parts shown in the exploded view of Fig. 4. In the bottom of the pad box is an inflatable bag or pad I00,

preferably formed of rubber and having a cavity which is thin heightwise of the pad. The infiatable bag is provided at its toe end with an air valv IOI which may be opened when the pad is being filled with water to permit the exhaust of air, and on the under side of its heel end is a suitable connection through which water or other fiuid may be introduced. The connection serves, as shown in Fig. 3, to clamp the inflatable pad I against the rear part 48 of the pad box and comprises a head I04 located inside the pad I00 and having passages I06 about its periphery commun-icating with a hollow stem I08. In the side of the stem are openings IIO communicating with a passage II2 to which a hose H4 is connected. The stem I08 is drawn down to cause the head I04 to force the rubber bag surrounding the stem into contact with the heel portion 48 by a screw II6 passing through the bottom of the heel portion 48 and threaded into the lower end of the stem I08.

On top of the pad I00 is a mask plate I I8 having a beveled edge I20 shaped to correspond roughly to the shape of the toe portion of a shoe and arranged for adjustment lengthwise of the pad. Pins I22 on the mask plate are connected by twisted links I24 to arms I26 upstanding from a rockshaft I28 (Fig. 12), the rockshaft having at one end a lever I30 by which the shaft may be turned to move the mask plate to various positions for different sized shoes, as indicated by a scale I32 with which a pin I34 carried by the mask plate (Figs. 4 and 7) cooperates. Unintended movement of the mask plate is prevented by-a friction plug I36 carried by the lever I30 and engaging a relatively fixed surface I38, as shown in Fig. 12. The mask plate II8 (Fig. 9) engages a rabbet formed in the part 44 which is slightly deeper than the thickness of the mask plate. On top of the mask plate and secured to the forepart portion 44 is a thin plate I40 and resting on this plate is a thick solid rubber pad I42.

The purpose of the plate I40 is to support the pad I42 out of contact with the mask plate II8 so that its adjusting movements will not be obstructed. The shank-and-heel portion of the pad I42 is provided with a downturned flange I44 (Fig. 4) which, when the parts are together, embraces the shank and rear portion of the pad I00. Between the pads I00 and I42 there is at the heel end a heel plate I46 which may be held in place by a piece of rubber-coated canvas I48.

The plate I46, which may be substantially rigid,

is for the purpose of preventing the heel portion of the pad from conforming to the shape of the shoe bottom while permitting the application thereto of considerable pressure. The pad I42 has in the shank portion a groove I50 which relieves pressure along the central portion of the shank and causes the shank pressure to be localized at the sides of the shank. The central portion of the forepart of the pad I42 may be reduced in thickness, as shown in Fig. 4, within the area indicated by the dotted line I52. Surrounding the forepart of the pad I42 is a plate I54 of slightly greater thickness than the pad I42, as indicated in Fig. 9, and over the plate I54 is arranged a plate I56 which projects over the marginal portion of the pad I00 to hold it in place and has its upper face rabbeted at I58 to receive the marginal portion of a pad cover I60, shown in Figs. 4, 9 and 10 as having in its forepart a plurality of thicknesses, the-upper thickness lying in the rabbet I58 of the plate I56. On top of the plate I55 and overlying the margin of the cover I60 is a cover plate I62 which is secured in place, along with plates I56, I54 and I40. by screws which extend through holes I64 formed at one side of each of the plates and are threaded into the pad box 44. At the opposite side the plates are secured by screws passing through similar holes I66 in all the plates.' The indicator I84 on mask plate II8 extends upwardly through slots I68 formed in each of the plates I40, I54, I66 and I62 and cooperates with the scale I32 to indicate the adjusted position of the mask plate. The various layersforming the pad are held in the pad box at the shank portion by plates I10 which are secured to the shank portion 46 with their edges projecting over the pad. The heel portion of the pad is held in place by a horseshoe-shaped plate "2 which is secured to the heel portion 48 of the pad box with its edge projecting over the pad. The cover I56 may be provided with a stud I14 which is adapted to enter a hole H6 in the pad I42 whereby the pad and its cover are properly located with respect to each other.

The cover plate I62 is provided with upstanding ribs I between which the shoe and sole gages are mounted to slide transversely of the pad to engage the sole substantially at the ends of the ball line. Between the ribs I80 at each side of the shoe is located first a sole gage I82 and above this a shoe gage I84 (Fig. 9), the gages being independently movable. The sole gage I82 at the outer end of the ball line is connected by a ball joint I86 to an arm I88. The sole gage I82 at the inner end of the ball line is similarly connected to an arm I90. These arms are connected, as shown in Fig. 6, to the upper ends of sleeves I92 mounted in bearings I94 formed in bosses on the part 44. The sleeves I92 at their lower ends are connected respectively to segments I96, I98 which mesh with each'other (Fig. 8) to produce equal and opposite movement of the sole gages I82. The shoe gages I84 are connected by ball joints 200 respectively to arms 202 and 204. The arm 202 (Figs. 6 and 8) is secured to the upper end of a shaft 206 passing through the sleeve I92 and has secured to its lower end a segment arm 208 which meshes with a similar segment arm 2I0 connected to a similar shaft 206 similarly mounted at the opposite side of the Dad.

The sole gages I82 are urged inwardly toward the shoe by a spring 2I2 (Figs. 5, 7 and 8) connected at one end to a pin on the segment I98 and at the other end to a pin M6 on the forepart portion 44, the tension of the spring being at least sufiicient to take up the backlash in the teeth of the segments I96, I98. The closing movement of the sole gages is controlled and their opening movement effected by a pin 2I8 on an extension 228 (Fig. 7) extending rearwardly with respect to the machine, of the segment I95 ,so that the pin is out of line with the shafts 286. The pin engages a slot 222 (Fig. 8) in a slide 224 arranged for movement longitudinally of the pad on the member 44, the slot being inclined at a small angle to the direction of movement of the slide. The slide 224 has pivoted thereto at 226 one end of a yoke-shaped link 228 the other end of which is pivoted by a pin 238 to a lever 232 (Fig. 7), said lever being fulcrumed to the base at 234 (Fig. on a common center with two other levers to be described, all of said levers having pins at their upper ends such as 238 which, in the normal position of the mechanism, are in line with the pivot 16 about which the forepart portion 44 is rocked by movement of the wedge 66 so that adjustment of the forepart member about its pivot does not afiect the mechanisms connected to and operated by the lever 232 and the two other levers. A link 236 is pivoted to the lever 232 between its ends by a pin 236 (Fig. 8) and extends forwardly to a point opposite the breast-line gages (Fig. 7) where it is pivoted to the upper end of an arm 248 the lower end of which is pivoted by a pin 242 (Fig. 5) to the base. As shown in Fig. 5, the arm 248 is hidden by a similar arm 244 and both these arms are engaged by a contact surface 246 on an arm 248 also pivoted at 242. The arm 248 is pivoted at 258 to an upright bar 252 (Fig. 16) downward movement of which swings the arm 248 clockwise to allow the ball gages I82 to be moved inwardly toward a sole on the pad partly by the spring 2I2 (Fig. 8) and principally by another tension spring 254 connected to the pin 238 at one end and at the other to an ear 256 on the arm 248 (Fig. 5). During movement of the arm 248 by downward movement of the bar 252 the spring 254 maintains the arm 248 in engagement with the contact surface 246 on the arm 248 and, through the link 236, lever 232 and link 228, moves the slide 224 forwardly, the inclined slot 222 acting on the pin 2l8 to swing the segment I96 counterclockwise (Fig. 8) about its center 286, thus causing the ball gages I62 to engage the sole on the pad, whereupon the contact surface 246 on the am 248 may continue its movement, separating from the arm 248 and further tensioning the spring 254 the tension of which up to the point of separation has remained substantially constant by movement of the ear 256 with the arm 248. This insures that the gages will remain in contact with the sole, the gages being locked against separation by reason of the small inclination of the slot 222 to the direction of movement of the s1ide224.

The gages for the end of the shoe and sole may, as illustrated, e similar to those disclosed in my Patent No. 2,262,759, granted November 18, 1941. The sole gages comprise '7) two pairs of plates 268, 262 pivoted by pins 264 to a supporting member 266 with their free edges in alinement and adapted, by reason of the pivots 264, to rest against the cover I58 of the pad. The free edges of one pair of plates form nearly a right angle with the free edges of the gagefor engagement with the toe end of the sole. Above the sole gages is a shoe gage 268 having shoe-engaging surfaces 218 arranged at the same angle to each other as the sole gages. Both the sole-gage-carrying member 266 and the shoe gage 268 are cut away in the region where their operating edges, if extended, would meet to provide an opening 212 through which the relative position of the shoe and sole may be observed by the operator. The shoe gage 268 is secured to a slide 214 by a screw 216 passing through a transverse slot in the gage 268 and threaded into the slide. The slide 214 is arranged to be moved in ways 216 formed on the supporting member 266 by a screw 288 threaded into the slide 214 and held from longitudinal movement by a pin 28! engaging a groove between the head of the screw 288 and a collar thereon. The supporting member 266 is provided with a pair of laterally extending arms 262 which are pivoted by pins 284 to upstanding ears on a member 286 which is secured by screws 288 to a sliding plate 298, the screws 266 passing through slots 292 in the member 286, which slots are perpendicular to the longitudinal median line of the forepart of a shoe placed on the pad. The plate 298 is mounted to slide longitudinally of the shoe in suitable slots 294 formed in upward extensions 296 on each side of the forepart member 44. As best shown in Fig. 12, the slots 294, while fitting the heightwise dimension of the plate 298, are extended laterally so that the plate has substantial floating movement laterally of the pad. The plate 298 is pivotally connected by twisted links 298 to upstanding arms 388 of a yoke 382 mounted to turn freely on the shaft I28, the pivots between the links and arms being rather loose to permit the lateral movement of the plate. It will be apparent that rocking the yoke 382 on its shaft I28 will move the plate and the shoe and sole gages mounted thereon longitudinally of the pad and substantially in the direction of the longitudinal median line of the forepart of a shoe or sole resting thereon, the plate 298, however, being free to move laterally to allow the sole gages to find the sole. To thus move the toe gages, one of the arms 388 has connected thereto midway of its ends a link 384 which extends forwardly (Fig. 7) and is pivoted to a lever 386 which, like the lever 232, is fulcrumed-to turn on the shaft 234. Connected to the lever 386 some distance below its upper end is a link 386 other pair so that together they constitute a V- which, at its forward end, is pivoted to the arm 244 which is similar to the arm 248. A tension spring 3I8 is connected at its rear end to an ear on the link 388 and at its forward end to an ear 3i 2 secured to the base, the spring tending to move the toe gages toward the shoe. Since the arm 244, like the arm 248, rests in contact with the arm 248, movement of the arm 248 by downward movement of the bar 252 will permit the spring 3| 8 to move the toe, shoe and sole gages toward the sole. After the gages meet the sole, they will be held against it by the spring 3") while the arm 248 continues its movement.

To lock the toe gages in operative position, the cover plate I 62 (Fig. 12) is slotted on its under side to receive cam levers 3I4 pivoted at 3I6 to ears projecting downwardly from the plate I62, the levers having surfaces at their upper ends which are eccentric with respect to the pivot 3I6 so that when rocked in a counterclockwise direction (Fig. 5) they will engage the plate 298 and lock it and, of course, the gages against movement. Each, of the locking levers 3 is connected y a link 3I8 to the upper end 01 an arm 326 by a pin 32I, each of said arms being pinned to the shaft 234 so that clockwise movement of one of the arms v326 will cause movement of both locking levers 3| 4 to lock the plate 296 near each of its edges. One of the arms 326 has pivoted thereto between its ends at 322 a link 324 which at its front end is pivoted to an upright arm 326 of an angle lever pivoted at 242, the other arm 328 of which is nearly horizontal. Mounted on the arm 248 is a sleeve 336 in which is a plunger 332 extending outside of the sleeve, the plunger being backed up by a spring 334. Late in the clockwise movement of the arm 248 the plunger 332 engages the horizontal arm 328 of the angle lever and moves it yieldingly downward and thus, through the links 324, 3I8, actuates both locking levers 3I4 for the plate 286. The gages are unlocked by a tension spring 335 connected at one end to the pin 322 and at the other to a fixed pin on the frame, the spring normally holding the lever 236 against an abutment 331 with the plate 296 unlocked.

As shown in Fig. 7, the sole gage arm I88 is provided with an upstanding lug 336 through which freely passes a thumb screw 338 which is threaded in a, lug 346 on the shoe gage arm 262, a compression spring 342 being located on the screw between the lugs. This construction causes the shoe gages to be closed equally and oppositely'by closing movement of the sole gages and permits adjustment of the shoe gages relatively to the sole gages to accommodate any projection of the sole beyond the shoe. Also, if the shoe gages I84 are not set at exactly the proper distance apart to receive the shoe, the

spring 342 can yield to permit the shoe to be pushed down between the gages into contact with the sole and centered with respect to the sole. Further relative adjustment between the sole gages I82 and the shoe gages I84 is provided by the construction best shown in Fig. 9. The sole gage I82 extends outwardly and is connected by the ball joint I86 to the sole gage arm I88. The shoe gage I84 is connected to a plate 344 having slots therein (Fig. '1) through which pass screws 346 which are threaded into a plate 348 and provided withnuts on their lower ends. The plate 348 is connected by the ball point 266 to the shoe gage arm 262. By loosening the screws 346 the shoe gage may be adjusted relatively to the sole gage. The gages are retained in position between the ribs I 86 by leaf springs 356 pivoted by screws 352 to the cover plate I62 and extending over the top of the shoe gages to press them downward yieldingly. The shoe-engaging faces of the gages I84 are upwardly and outwardly inclined to facilitate the passage of the shoe down between them and the wedging of them apart if they are set somewhat too close together.

Referring to Fig. 8, it will be seen that the gage arm I88 has a downward extension 354 on which is a fork embracing a pin 356 mounted in a slide 358 which is arranged in guides 366 (Fig. 5) formed on the under side of the forepart portion 44 of the pad box. On the'inner end of the slide 358 (Fig. 8) are downwardly projecting disk-like plates 36I between which extends a rounded end of a bent bar 362 extending to the rear end of the pad box where it is provided with a pin 364 entering a slot 366 in a supporting member 368, the pin preventing movement of the bar lengthwise of the pad box but permitting its rear end to swing sidewise by reason of the slot 366. The bar 362 is provided with a slot 316.

A sliding member 312 has an edge 314 formed to engage a slot 318 formed in the upper side of the supporting member 366, the sliding member being. provided with a thumb setscrew 318 to hold it in position on the supporting member 368. The sliding member 312 extends under the supporting member 368 and carries a pin 366.

which extends upwardly through the slot 316 in the bar 362 and into a slot 882 formed in the supporting member 366, the pin thus providing an adjustable fulcrum for the bar 362. The

member 366 has on its upper side an ear 384 (Fig.

5) which'is pivoted by a pin 386 to a downwardly projecting, arm 388 formed on a transverse slide 386 which carries the gages at the rear end of the shoe. Between its ends the bar 362 has an upwardly projecting pin 892 (Fig. 8) which engages a fork 394. one slide 396 arranged to slide transversely of the shoe in ways 398 formed on the under side of the heel portion 48 of the pad box (Fig. 5).

At its outer end the slide 396 has an upward projection 466 (Fig. 8) carrying an ear 462 pivoted to downwardly projecting ears on a member 464 upon which is mounted the breast-line gage for the outer side of .the sole. As best shown in Fig. 7, the member 464 is provided with suitable ways to receive a slide 486 having an upstanding ear 488 threaded to receive a thumb screw 4I6 which is prevented from longitudinal movement by a pin 4I2 located between two collars formed on the screw. Between the ear 468 and the inner collar on the screw is a spring M4 to prevent accidental turning of the screw. On one of the ways in which the slide 466 is mounted is a scale 4I6 with which a pointer on the ear 488 cooperates to indicate the adjustment of the slide effected by turning the screw. A member M8 is slotted to receive a screw 426 which passes through the slot and is threaded into the slide 466 and a breast-line gage- 422 is riveted at 424 to the member 4I8. Both breastline gages are preferably of the collapsible type disclosed in United States Letters Patent No. 2,186,961, granted January 16, 1940, in my name. It will now be seen (Fig. 8) that, when the slide 358 is moved inwardly by closing movement of the sole gage arm I88, this movement will be communicated to the lever 362 which, swinging about its fulcrum 386, will, through the pin 382, move the slide 396 carrying the breast-dine gage inwardly a distance less than but-proportional to the movement of the sliding member 358. Usually, since the change in widthwise dimension between successive sizes of soles at the ball line is about twice the change in widthwise dimension at the point'where the breastline gage contacts with it, the ratio of the movement of the slide 358 to that of the slide 386 will be 2 to 1 but, for other conditions, the ratio may be varied by changing the position of the fulcrum 386 which may be adjusted by loosening the thumb screw 318 and moving the fulcrum pin 386 to a different position in the slot 316. Since the slide 358 is mounted on the forepart portion 44 of the pad box and the slide 386 and the bar 316 are mounted on the heel portion 48 of the box, there will be relative movement between the slide 358 and the bar 362 when the forepart portion is adjusted up and down by movement of the wedge 66. This is provided for by the construction described in which the rounded end of the bar 362 engages what is in efiect a vertical slot between the disk-dike plates 36L To support the bar 862 adjacent to its rounded end it is provided with a strut 426 which rests on a stationary horizontal surface428 formed on the base of the pad box. Preferablythe bar 362 is held by a tension spring 426 in engagement with the outer one of the plates 36l so that lost motion of the bar will be prevented.

A breast-line gage 436 (Figs. and 7) for' 448 to the slide 396. The segment arm 446 car.

- median line of the rearpart with themedian ries a pin 456 which is held in abutting relation to a projection on'the arm 442 by a tension spring 452 having its ends connected respectively to pins on the arm 442 and the segment arm 446. Opposite the arm 442 is a similar arm 454 on an angl lever pivoted at 456 to the slide 396, the shorter arm 458 of which is formed as a segment meshing with the seg-' ment arm 446. The end of the arm 454 is connected by a pin 466 to a link 462 the other end of which is bent downwardly (Fig. 8) to enter .a vertical hole in the upward projection 466 (Figs. 7 and 8) so that movement of the slide 396 as described will impart movement to the connected between the pin 412 and the pin 466,

to hold the outer breast gage 422 in contact with the pad.

In most lasts the forepart is twisted about its longitudinal axis with respect to the heel part so that the side of the last bottom corresponding to the ball of the great toe is lower than the opposite side which corresponds to the little toe. This condition is recognized in the present construction in which, as shown in Fig. 12, the forepart pad box 44 and the mechanism associated therewith are laterally inclined to the supporting plate 42 at a small angle which, as illustrated, is approximately 2 degrees. Thus, the left-hand side of the forepart of the right-hand pad box, when viewed from the operator's position, is a little lower than the opposite side and distortion of the pad will result and the pressure will be more evenly distributed upon the shoe bottom. It is understood, of course, that the surface of the pad in the heel portion 46 of the pad box is laterally parallel to the supporting plate 42.

The rear end of the heel portion 48 is provided with a T-guide' 468 (Fig. 5) .which is curved from a center (Fig. 7) located substantially at the in tersection of the median line of the heel part with the median line of the forepart of a sole placed on the pad, and the slide 396 is provided with a complementary Tway 416 engaging the T-guide, the slide being held in adjusted position on the guide by a thumb set-screw 412 threaded through the slide and engaging the T-guide 468. The

' V slide 396 and the gages carried thereby are thereline of the forepart of a shoe and sole placed on the pad.

A V-gage 414 for the rear end of the shoe (Figs. 5 and 7), has a square stem 416 arranged to slide longitudinally of the shoe between guides 418 formed on the slide 366. The stem 416 is held in place between the guides by a toothed plate 486 secured to one of-the guides by screws 462 and extending over the stem 416. Onthe upper side of the stem 416 is an ear 484 to which are pivoted bifurcations of a lever 486 by a pin 483. At ofie end of the lever, which is sustained by a spring 496, is a finger piece 492 (Fig. 5) and at the opposite end of the lever is a pawl 494 engaging the teeth of the plate 486. After a shoe has been placed upon a sole on the pad, the finger piece 492 is depressed and the V-gage 414 moved toward the shoe. When the V-gage meets the shoe, it-will centralize its rear portion with respect to the sole as located by the breast-line gages 422, 436 and, upon release-of the finger piece, will be held in locked position by thepawl 494. When the shoe'is to be removed, the pawl is released and the V-gage moved away from the shoe by a handle498 fixed to the rear end of the stem 416. A stop pin 566 on the lower side of the stem 416 engages the slide 39,6 to prevent the V- gage 414 from beingpushed forwardly of the shoe beyond its guideway.

The gage-operating bar 252 is pivoted at its lower end by a pin 562 to an arm 564 (Figs. 15 and 19) which is fulcrumed on a shaft 566 supported v by hearing barckets 568 projecting downwardly hence when pressure is applied to the shoe less (Fig. 2) from a supporting partition 5 l 6 extending across the housing or frame 46. Fulcrumed on the same shaft 566 is a lever 512 to the front end of which is pivoted a rod 5. the lower end of which is connected by a pin 5l6 to a treadle lever 5l8 fulcrumed at 526 to lugs on the under side of the frame 46 and having its front end formed as a foot piece 522. The treadle lever 5 I8 is raised by a tension spring 524 connected at its lower end to the pin 5l6 on the lever and at its upper end to an eye 526 on the frame. The arm 564, and consequently the bar 252, are normally held raised by a tension spring 528 connected at its lower end to the pin 562 and at its upper end to an eye 536on the frame. Beside the arm 564 (Fig. 15) is a'lever 532 fulcrumed on the shaft 566 and having its rear-arm (Fig.- 36) pivoted at 534 to a link 536 which at its lower end is pivoted to a piston 538 in a cylinder 546. The rear end of the lever is held down by a spring 542 connected 532 and extending through a slot 556 in the bolt cylinder 546 by a valve shown in Figs. 17 and 18.

Communicating with the lower end of the cylinder is a pipe 554 having therein a septum 556 (Fig. 18). At one side of the septum 556 are ports 558 and on the other side of the septum are ports 568. Arranged to slide on the pipe 554 is a sleeve valve 562 having inside of it an annular recess 564 wide enough to cover both ports 558, 568 so that in the position shown in Fig. 18 pressure on the outside of the septum can pass through the ports 558, the annular recess 564 and the ports 568 into the cylinder548. When the sleeve 562 is slid to the right, however, the ports 568 (Fig. 1'7) are opened to permit oil to be exhausted from the cylinder and the ports 558 are closed. To slide the valve from one position'to the other, it is provided with an annular groove 566 which is engaged by pins 568 in the arms of a forked angle lever fulcrumed at 518 to a bracket 512 on the under pressure into the cylinder 548 and causing the bolt 544 to move downwardly, carrying with it the arm 584, thus depressing the bar 252 to cause operation of the gauges as described.

To hold the gages in operative position, means shown in Figs. 19 and is provided for locking the bar 252 when depressed. The gage-operating bar 252 has a contact piece 518 inserted therein and held by screws 588. Upward movement of the bar 252 in response to the spring 528 is limited by engagement of a ledge 582 on the contact piece 518 with a pawl 584 pivoted-by a pin 586 to a bracket 588 formed on a cylinder 598 which is secured to the supporting partition 518. A lever 592 fulcrumed on the pin 586 is heldpy an adjustable tension spring 594 with a surface 596 thereon in-contact with the top of the cylinder 598. The lever 592 has a downward projection 598 between which and the pawl 584 is a compression spring 688 tending to turn the pawl clockwise. When the bar 252 is drawn down as described, the pawl 584 engages a notch 682 in the contact piece 518 and locks the bar in depressed position. Should the operator desire to release the gages before proceeding with the operation, the pawl 584 may be released by depressing a handle formed on a forwardly extending rod 684 which is threaded into a lug 686 on the upper side of the lever 592. When the lever 592is thus rocked about the pivot 586, it engages an upward extension 688 on the pawl 584 and withdraws it from the notch 682, thus permitting the bar 252 to be raised by the spring 528. In the normal operation of the machine, the pawl 584 is released at the proper time by introduction of oil under pressure through a pipe 6l4 into the cylinder 598 in which is a plunger 616 which is raised by the oil pressure to engage the lever 592 and releasethe pawl 584.

The means for applying pressure to the shoe (best shown in Figs. 2 and 3) comprises a member or head 618 (Fig. 2) having thereon an abutment 628 to engage'the cone of the last and an abutment 622 to engage the toe portion of the shoe. The abutment 622 is carried by a slide 624 arranged to move longitudinally of the shoe on guides 626 formed on the head. The slide 624 is connected by a link 628 to a pin 638 eccentrically mounted with respect to a shaft 632 extending through the head and provided with a hand wheel 634 so that by turning the hand wheel the slide 624 and the abutment 622 may be moved longitudinally of the shoe to locate the abutment properly with respect to shoes of different sizes. Accidental turning of the hand wheel is prevented by a compression spring 636 mounted on the shaft 632 between the hand wheel 634 and the head 6I8. The head (H8 is pivoted at 638 at each side of the pad to a bar 648, which bars at their lower ends are pivoted at 642 to a cross head 644. The bars 648 are normally supported against depression by rolls 646 on their inner sides which engage ledges 6481on the plate 42. To bring the abutments 628, 622 into position over the shoe,

648 and the machine frame. When in this position the rolls 646 overlie the ledges 648 which prevent the head 6l8 from being moved downward when in that position.

When the head is released and drawn back as described, it may be in such a position about its pivot 638 that the abutment 622 will strike the gage mechanism. To prevent this an arm 654 connected to the head 6!!! is pivoted to a link 656 having a slot 658 at its lower end. An angle lever pivoted at 668 to the frame has on one arm a pin 662 engaging the slot 658 and has its other arm connected by a link 664 to the bar 648. As the bar 648 is swung toward the position shown in Fig. 2, the pin 662 engages the upper end of the slot 658, pushing upwardly on the link 656, thus tipping the head 6! in a counterclockwise direction to prevent the abutment 622 from hitting the gages. The link 656 is provided with a yielding element 666 arranged to permit lengthening of the link when necessary but preventing its being shortened.

The crosshead 644 (Fig. 3) and connected mechanism, including the shoe abutments, are held raised by a pair of tension springs 668 connected at their lower ends to eyes 618 on the crosshead, and at their upper ends to eyes 612 on the cover plate 42 (Fig. 2). Cylindrical bores 614 are formed in the downward projection of the plate 42 to form cylinders the longitudinal axes of which are perpendicular to the plate 42. In the cylinders are plungers 616 bearing at their lower ends on the crosshead 644. The upper ends of the cylindrical bores are closed by plugs 618 and oil under pressure is admitted above the plungers through a pipe 688 which has two branches one of which is connected to one oil the cylinders and the other branch to the other cylinder, the point of connection being at 682 near the upper end of each cylinder. the plungers 616 is a cylindrical strut 664 the reduced lower end of which extends through the crosshead 644 and is held therein by a nut 686, being held from turning by a Woodruil? key 688. The strut passes upwardly through a cylindrical bore 698 in the member in which the cylinders are formed, the strut being prevented from tuming in the bore 698 by a spline 692. The upper end of the strut is provided with a groove 694 Between v
